I have a strange new issue that has been plaguing me for a few weeks now. I have a 2003 f250 6.0L with 213k. Half the time, it starts right up with the ignition, no problem. Sometimes I turn the key and get no crank. Usually I can bypass the ignition by touching the solenoid wire (passenger side) to the pos battery terminal with the key in the run position, and it starts right up. On 2 occasions, however (including right now), that trick fails and I'm stranded for a few hours until the truck decides it will start again.
As soon as the issue began, I replaced my starter with a reman from O'Reilly's. When this didn't solve the problem, I replaced the batt to batt, starter, solenoid pos wire with the genuine Ford cables. Now it starts more often with the key only, but still not 100%. I've ordered new neg batt cables because I noticed one has 3 inches of corroding, exposed wire! Also ordered a new relay for slot 307 in fuse box.
Finally, I've burned through 4 alternators in 2 years, and now I'm thinking my wiring may have been the culprit all along!
Any suggestions for what else this problem could be? If my new cables and relay don't fix it, then I'm not sure where to look next.
